mnemonic in Context To help remember the levels of biological classification, James taught his students the mnemonic sentence “King Philip Came Over For Good Spaghetti” (Kingdom, Phylum, Class, Order, Family, Genus, Species). What are the 12 levels of biological organization from smallest to largest? The levels, from smallest to largest, are: molecule, cell, tissue, organ,…

A G3P molecule contains three fixed carbon atoms, so it takes two G3Ps to build a six-carbon glucose molecule. How many carbon are there in glyceraldehyde 3-phosphate? molecule of the three-carbon compound glyceraldehyde-3-phosphate (Gal3P). This three-carbon sugar phosphate usually is either exported from the chloroplasts or converted to starch inside the chloroplast. What is glyceraldehyde…

Many adult adoptees have actively searched to locate their Birth Mothers for different reasons. Some seek medical knowledge, others want to know more about their family history. But primarily, adoptees have a genuine curiosity of who their Birth Mother is; appearance, personality, abilities. How many adopted children look for their biological parents? The reason they…

How do you get mRNA from DNA? mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. What…

The Virial Equation’s significance is its ability to compute total kinetic energy for a complex system of particles without having to consider the individual interactions of its particles. What does 2nd virial coefficient signify? The second virial coefficient describes the contribution of the pair-wise potential to the pressure of the gas. The third virial coefficient…

A biological psychologist researches brain functions to understand human behaviors and how the effects of mental illnesses or injuries can cause a response in human behavior. Biological psychologists may work on medical treatments to assist with therapies or rehabilitation programs. What can you do with biology and psychology? Research assistant. Neuro rehabilitation manager. Mental health…

Consistency Index (CI)- This is a measure of how well an individual character fits on a phylogenetic tree. It is calculated by dividing the minimum possible number of steps by the observed number of steps. What is the consistency index? Consistency index or relative consistency is the liquid limit of the soil, minus the natural…

Several factors contribute to species diversity, including habitat diversity, competition among species, and genetic diversity. Genetic diversity within a species not only is necessary to maintain diversity among species,6 but also contributes to the diversity of food, fiber, and medicines available from nature. How does oil drilling affect biodiversity? Roads built for drilling increase human…

In spite of these challenges, the US government has options for increasing the likelihood that biological attacks can be prevented, through maintaining international norms and improving surveillance systems, deterring potential adversaries by demonstrating a strong national response, developing better forensic analysis … Is biological warfare illegal? In particular, the 1972 Biological Weapons Convention (BWC) bans…

For every pound of BOD5 (5-day Biochemical Oxygen Demand), about two pounds of oxygen are required for complete digestion. How does biological nutrient removal work? Biological nutrient removal (BNR) removes total nitrogen (TN) and total phosphorus (TP) from wastewater through the use of microorganisms under different environmental conditions in the treatment process (Metcalf and Eddy,…

Main Difference – Template vs Coding Strand The template strand runs in 3′ to 5′ direction. The other strand in double-stranded DNA, which runs from 5′ to 3′ direction is known as the coding strand. The template strand is responsible for the amino acid sequence in synthesizing the polypeptide chain. What is a template strand…

According to ETIB, the number of species present on an island is determined by a balance between immigration and extinction. Generally, as the number of species present increases, the immigration rate decreases and the extinction rate increases. What biological factors determine the immigration and extinction rates?
